  1. CGSE researchers win 2 awards in the 2016 ICE Publishing Awards

    CGSE academics have been recognised for their high quality research publications in the 2016 Institution of Civil Engineers Publishing Awards.COFS-150225-54

    Dr Yinghui Tian, Prof Mark Randolph and Prof Mark Cassidy received the David Hislop Award for the best offshore paper in Géotechnique. Their paper, Analytical solution for ultimate embedment depth and potential holding capacity of plate anchors, is now available to download free of charge here. The paper proposes an analytical approach to evaluate the ultimate embedment depth and holding capacity that plate anchors can potentially achieve.

    Dr Shiaohuey Chow, Dr Conleth O’Loughlin and Prof Christophe Gaudin, along with co-authors Mr Riccardo Corti and Dr Andrea Diambra from the University of Bristol were awarded the Telford Premium award for their paper in Géotechnique Letters.  The paper, Drained cyclic capacity of plate anchors in dense sand: experimental and theoretical observations, provides experimental evidence and proposes a macro-element theoretical model that shows and explains that the drained cyclic capacity of a plate anchor in dry, dense sand may be higher than the equivalent monotonic capacity. Dr Diambra will be visiting COFS later this month to strengthen the collaboration that led to this award winning paper.

    The ICE Publishing Awards acknowledge the best work published in ICE journals. The awards will be presented at a ceremony in London in October. The full list of award winners can be viewed at ICE Publishing Awards 2016.

  7. Dr Shiaohuey Chow receives grant to investigate plate anchor behaviour in sand

    CGSE academic Dr Shiaohuey Chow has received a University of Western Australia Research Collaboration Award to collaborate with Dr Andrea Diambra of The University of Bristol. The project “Plate Anchors for Offshore Renewable Energy Application: Predicting Cyclic Behaviour in Sand” will use centrifuge and numerical modelling to investigate the behaviour of plate anchors in sandy soils.plate anchor

    Plate anchors have traditionally been used in hydrocarbon exploration to moor large floating structures in deep water clayey soils, but they also provide a promising anchoring solution for the shallow, sandy seabeds typically associated with renewable energy devices.

    This new research project will use centrifuge modelling to understand the undrained cyclic capacity of plate anchors in sand. Once the results of the centrifuge modelling have been established, Dr Chow and Dr Diambra will use the University of Bristol’s hardening memory surface (HSM) model to develop and validate a macro-element model that will simulate the progressive deformation and strength changes induced by cyclic loads on plate anchors.

    Offshore renewable energy sources have the potential to contribute to meeting increasing global energy demand, and government targets for clean energy.

  8. Fugro scholarship awarded

    Mr Wangcheng Zhang, a PhD candidate based at the Centre for Offshore Foundation Systems (COFS), is the inaugural recipient of the Fugro Scholarship in OffsWangchenghore Geotechnics. The scholarship is designed to assist in addressing key questions relating to design and performance in the field of offshore geotechnics, and to reduce risk by enhancing engineering design across the offshore sector.

    Under the supervision of the Fugro Chair in Geotechnics, Professor Mark Randolph, and co-supervised by Dr Dong Wang (COFS) and Professor Sasha Puzrin (ETH Zurich), Wangcheng will explore the initiation of submarine landslides and develop recommendations to improve the identification of zones of the continental shelf break that have increased submarine landslide risk. Submarine landslides are of great concern in deep water oil and gas developments and are also among the most challenging of natural hazard risk to quantify. This is due to difficulties in predicting their occurrence, and their potentially devastating consequences including collision with oil and gas pipelines or the generation of tsunamis.

    Fugro and COFS work together to sustain a research group that is committed to supporting Fugro’s activities worldwide. This partnership has put Australia on the global geotechnical map and supports the international geotechnical community and offshore projects in the oil and gas and renewable energy industries.

  9. CGSE PhD student, Jingbin Zheng, awarded ISOPE scholarship

    2015-05-15 Jingbin photo at DSME_smallCGSE PhD student, Mr Jingbin Zheng, has been awarded a 2015-2016 ISOPE scholarship for Outstanding Students. The scholarship is in recognition of outstanding academic achievement and the potential to become a leader in the offshore mechanics and polar engineering field.

    Jingbin co-authored the paper Installation of Spudcan Foundations in Layered Soils: Centrifuge Test and Numerical Analysis, with CGSE researchers Shazzad Hossain, Stefanus Safinus, Youngho Kim and Jonghwa Won, Jong-Sik Park and Min Jung Jun from Daewoo Shipbuilding and Marine Engineering in Korea. The paper is being presented at ISOPE 2015.

    Jingbin’s PhD topic is on the numerical modelling of spudcan and cone penetration in multilayer soils. Using numerical analyses of spudcan and cone penetration tests, Jingbin is producing practical predictive methods for assessing spudcan penetration resistance in multilayer soils. These include a mechanism-based two-step approach and a CPT-based direct approach. The former predicts spudcan penetration resistance using shear strength parameters derived from laboratory tests, while the latter will provide a direct correlation between spudcan penetration performance and field penetrometer data to provide a first-order estimation for the risk of punch-through failure and thus reducing the time scale and costs of current engineering calculations.

    The CGSE would like to congratulate Jingbin on his ISOPE scholarship award.
